As the Chief Historian in Li Ke's residence, Quan Wanji should have rectified Li Ke's behavior. His failure to uphold Li Ke's morals is a crime worthy of death! Li Shimin said this, mostly to save his own face - it was not his son's fault for the error, but that of the people around him who failed to advise him properly.
Liu Fan, as straightforward as Wei Zheng, immediately retorted, "Even Fang Xuanling, serving Your Majesty, cannot stop you from hunting, how can we solely blame Wanji!"
His point was that Fang Xuanling was an Imperial Minister and still unable to stop Your Majesty from hunting, how could we solely blame Quan Wanji for his crime!
Fang Xuanling, who was directly named, remained unfazed, imperturbable as thunder.
